fix(ios): add debug logging and fix storyboard ViewController class

Added debug logging to diagnose WebView loading issue:

Debug Logging:
- Added print statements to check bridge and WebView initialization
- Logs WebView URL to see if HTML is being loaded
- Helps diagnose if bridge is nil or WebView isn't configured

Storyboard Fix:
- Changed customClass from CAPBridgeViewController to ViewController
- Changed customModule from Capacitor to App
- Ensures storyboard uses our custom ViewController class

Fixes:
- WebView debugging: can now see if bridge/WebView are initialized
- Storyboard configuration: uses correct ViewController class
- HTML loading: helps diagnose why HTML isn't displaying

Result: Can now see in logs if WebView is being initialized correctly
